PHD 2000 Pump driver change infuse rate

Thank you, nathand. I was actually able to use a few commands on the hyper terminal window but, they were all related to reading the version of the PHD software or what the current settings are.  I'll have to figure out how to use visa, as this is the first instance that requires a direct use of it.

I was asked in a private message if I could share the VI that I wrote to drive this pump. Here it is, along with an image showing how it was used in the larger application. Sorry for the missing type definitions, just unlink them. The "Lane" input was particular to the system in which this was used - we had 4 of these pumps with the communications link daisy-chained between them and the Lane specified which pump to address. You'll of course still need to read the manual to determine the correct commands to send. I wrote this a few years ago and no longer remember the response format nor why all the string manipulation was necessary, but it did work.

One additional note. For my code above to work, you need to configure the serial port including termination character, as shown:

Hey nathand, could you give some hints on using Hyperterminal to communicate with pump? I wrote some simple LabVIEW code to control (run and stop) the pump but it works sometime and sometimes don't.
